This polymerase contains four catalytic subunits and a single regulatory subunit known as sigma (s). Interestingly, several distinct sigma factors have been identified, and each of these oversees ...

Researchers have revealed the structure of U11 snRNP – one of the five subunits of the minor spliceosome, which initiates the intron selection process.

It helps to properly fold the DNA and thus regulate gene activity. Cohesin contains two very similar subunits, STAG1 or STAG2 ...

In this diagram of G-protein-coupled receptor activation, the alpha, beta, and gamma subunits are shown with distinct relationships to the plasma membrane. After exchange of GDP with GTP on the ...

Endosomal recycling is a branch of intracellular membrane trafficking that retrieves endocytosed cargo proteins from early and late endosomes to prevent their degradatio ...
